Gateway Location Register (GLR)

TOMIA’s GLR controls inbound roaming traffic to help visited network operators increase roaming revenues from visitors on their network and reduce associated costs.

The complete signalling interworking and inbound roaming solution

GLR is a gateway between the Visited and Home Networks, which may be used to optimize the network registration process and handle the subscriber profile data across network boundaries. Once a subscriber registers to an operator’s network, TOMIA’S GLR starts to optimize the signaling traffic and keep the active subscriber in the visited operator’s network. Signalling optimization is becoming increasingly important as IoT traffic rises.

Thanks to the unique architecture, many customized proxy solutions can be implemented to overcome compatibility issues between the home and visited networks.
